So, what you can do right now is:Get the "Limited Support" achievement (play 1 assault card on mission 1)Play the Card "Infantry" on mission 28 and win.Get Brute Strength by using only the basic attack (no skills can activate). Easy on mission 1.Get Battle Medic by finding a player on the arena with no defence, then playing 3 medics and an assault card.

For decks, I think you have a good Imperial deck going, with some good cards from other factions.

I pretty much agree with the above analysis, with the possibility of replacing Thadius with Atlas (Atlas removes the possibility of a first turn Hunter becoming a problem). Another possibility being replacing the Bazooka Marine with Pandemic (if you'll be running your deck on manual), but switch if back out when you're not on, because the AI fails miserably with using action cards.
